Answer:

The tangent of ∠L represents the ratio between side NM and side LN.

The value of this tangent is 0.9028

Step-by-step explanation:

The angle ∠N is 90°, so we have a right triangle. In a right triangle, the tangent of an angle represents the ratio between the opposite side of that angle and the adjacent side (the cathetus, not the hypotenusa) of that angle.

So, in the triangle LMN, the opposite side to the angle ∠L is NM, and the adjacent side is LN (ML is the hypotenusa, because it is the bigger side). The value of this tangent is:

tan(L) = NM / LN = 65 / 72 = 0.9028

Answer:

65/72

Answer:

Volume, [tex]V=889.7\ m^3[/tex]

Step-by-step explanation:

From the attached figure,

Radius of shape is 5 m

Height of the cylindrical part is 8 m

It is required to find the volume of the given shape. The volume of the given object is equal to the sum of volume of cylinder and volume of hemisphere. So,

[tex]V=\pi r^2h+\dfrac{2}{3}\pi r^3\\\\V=3.14\times (5)^2\times 8+\dfrac{2}{3}\times 3.14\times 5^3\\\\V=889.7\ m^3[/tex]

So, the volume of the figure is [tex]889.7\ m^3[/tex].

Answer:

2

Step-by-step explanation:

The answer is 2 because the expression tells you that the numbers in parentheses are the ones you start with first. In this case you need to start from left to right since both sides are in symbols.

The airplane is 48 feet long in real dimensions.

To find out how long the airplane actually is, we can use the scale and input our amount of inches that it is measured by.

So, 1 inch equals to 6 feet.

Our model plane is 8 inches.

Now, we plug it in.

8 inches = 6(8)

8 inches = 48 feet

Therefore, the length of the real airplane is 48 feet.

48 feet

Answer:

48 feet

Step-by-step explanation:

Let's create a proportion using the following setup.

inches/feet=inches/feet

We know the scale is 1 inch to 6 feet. We also know that the plane is 8 inches long, but we don't know how many feet long it is, so we can say x feet.

1 inch/6 feet= 8 inches/ x feet

1/6=8/x

Cross multiply. Multiply the numerator of the first fraction by the denominator of the second. Multiply the denominator of the first by the numerator of the second.

1*x=6*8

x=6*8

x=48

Add appropriate units, in this case: feet.

x= 48 feet

The actual airplane is 48 feet long.

Answer:

[tex]=31.64ft^2[/tex]

Step-by-step explanation:

Triangle

[tex]A=\frac{h_{b}b }{2} \\=\frac{4*6}{2}\\=12ft^2[/tex]

Semicircle

[tex]A=\frac{\pi r^2}{2}\\=\frac{\pi 2.5^2}{2} \\=9.82ft^2\\[/tex]

because both semicircle are the same just multiply by 2

[tex]9.82*2\\=19.64ft^2[/tex]

Now add all together

[tex]12+19.64\\=31.64ft^2[/tex]

Answer:

31.64 ft*2

Step-by-step explanation:

Break down the problems by shapes-

1. Triangle= 4 x 6/2

=12 ft*2

2. Semi-Circle= 2.5/2 (sense their are two, we only need to solve one)

=9.82 ft*2

Multiply 9.82 by 2  

=19.64 ft*2

Adding all together

12+ 19.64

=31.64 ft*2

Answer:

(2,7)(3,2)

Step-by-step explanation:

Answer:

546 ft³

Step-by-step explanation:

In the figure attached, the top view of the pool is shown. It can be decomposed into a trapezoid which height is 12 ft and which bases are 9 ft and 11 ft; and a rectangle which height is 1.5 ft and and it base is 11 ft.

Area of the trapezoid: (9 + 11)/2 * 12 = 120 ft²

Area of the rectangle: 1.5*11 = 16.5 ft²

Total area: 120 + 16.5 = 136.5 ft²

Volume of the pool: Total area * deep = 136.5 * 4 = 546 ft³

The relationship between [tex]\angle 1[/tex] and [tex]\angle 8[/tex] are Alternate Exterior Angles.

Step-by-step explanation:

Alternate Exterior Angles, are pair of angles that lie on the outside of the traversal and lie on the opposite sides.

The required name of the relationship between 1 and 8 is alternate exterior angles

The correct option is (c)

When a transversal cut the pair of parallel lines then the alternate exterior angles are congruent.

Consider the given pair of parallel lines and transversal

we have

angel 1 and 5 are corresponding angles

angle 2 ad 6 are corresponding angles

angle 1 and 8 are alternate exterior angle

angle 2 and 7 are also alternate exterior angle

Therefore the correct option is (c)

Answer:

Step-by-step explanation:

geometric

equation

a1(r)^n-1

-1/2(2)^8

Given sequence is -1/2, -1, -2, -4,...

We get,

a1 = -1/2

r = 2

n = 8

So,

a8 = a.r^(n-1)

a8 = -1/2 * 2^(8-1)

a8 = -1/2 * 2^7

a8 = -1/2 * 128

a8 = -64

Therefore, 8th term of the sequence is -64

Answer:

The correct options is (a)

The simplified form of the given expression (2ab/a⁻⁵b²)⁻³ is b³/8a¹⁸. The correct answer is option A.

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The expression is given as follows:

(2ab/a⁻⁵b²)⁻³

= [(2ab) / (a⁻⁵b²)]⁻³

Use the negative exponent rule: a⁻ⁿ = 1/aⁿ and simplify the denominator

= [(2a.a⁵b) / (b²)]⁻³

Combine the coefficients 1 and 5 to get

= [(2a⁶) / (b)]⁻³

= 1/[(2a⁶) / b]³

= 1/[(2a⁶)³ / b³]

Cube the resulting expression to get

= b³/8a¹⁸

Therefore, b³/8a¹⁸ is the simplified form of (2ab/a⁻⁵b²)⁻³.

Hence, the correct answer is option A.

b) 9 cm^2

c) 9 cm^2

d) 60.39 cm^2

Step-by-step explanation:

a) the the length is 12 cm and the width is 6 cm. Area = lw

A=(12)(6)

A=72 cm^2

b) base equals 3 cm

Height equals 6 cm

A=1/2(3)(6)

A= 9 cm^2

c) base = 3 cm

height=6 cm

Area=1/2(3)(6)

A=9 cm^2

d) to to find the area of the parallelogram, You need to use Pythagorean theorem for one of the triangles.

3^2 + 6^2 = x^2

9 + 36 = x^2

45=x^2

✓45 = ✓x^2

x = 6.71 cm
